MPR03X OVERVIEW

The MPR03X is an Inter-Integrated Circuit Communication (I2C) driven Capacitive Touch Sensor Controller, optimized to manage two electrodes with interrupt functionality, or three electrodes with the interrupt disabled. It can accommodate a wide range of implementations due to increased sensitivity and a specialized feature set.

Features

• 8 µA supply current with two electrodes being monitored with 64 ms response time and IRQ enabled

• Compact 2 x 2 x 0.65 mm 8-lead µDFN package

• Supports up to 3 touch pads

• Only one external component needed

• Intelligent touch detection capacity

• 4 µA maximum shutdown current

• 1.71 V to 2.75 V operation

• Threshold based detection with hysteresis

• I2C interface, with optional IRQ

• Multiple devices in a system allow for up to 6 electrodes (need MPR032 with second I2C address)

• -40°C to +85°C operating temperature range

Implementations

• Switch Replacements
